加筋散粒体材料力学性能的大型三轴试验研究

Study on Big-scale Triaxial Test for Mechanical Behaviour of Reinforced Particulate Material

着重研究了风积砂、加筋风积砂、砂砾、加筋砂砾等几种散粒体材料的强度和变形性能,分析了加筋对材料强度和应力-应变关系的影响。研究表明:通过三轴试验可以获得散粒体材料的强度参数c和!;同时,可以拟定材料本构关系的各主要参数。

Behaviour of particulate material such as sand and grit, geogrid reinforcement were researched. Effect of reinforcement on particulate material strength and constitutive relation was studied. It is found that particulate material trength and constitutive relation parameters can be decided by big-scale triaxial test.
